Just four days after re-signing with the Patriots, the cornerback suffered a second hamstring injury during New England’s 28-20 win over the New York Giants and was subsequently informed of his release, according to a source.

Morris first injured his hamstring in late July after signing with the Patriots as an undrafted player out of Penn State and was released on Aug. 1. The second injury comes at an inopportune time, as rosters must be trimmed down to 53 names by Saturday afternoon.

After returning to practice Monday, Morris told MassLive.com that his first release taught him quickly about the business side of football. He indicated that other teams around the league inquired about his services during his layoff, but he held out for a second offer from the Patriots.

“I didn’t want to have to start over,” Morris said. “It felt right here, and I didn’t want to have to start over with a new playbook and everything.”

At Penn State, Morris played under former New England offensive coordinator Bill O’Brien, which gave him some familiarity with the Patriots’ system coming into camp.

The 5-foot-8, 186-pounder was honorable mention All-Big Ten as a senior. He finished his collegiate career with 148 tackles, one interception and 13 passes defensed.
